After years of development, foam sculptures have evolved from a single festive decoration model to a multi-dimensional development. With its strong operability and convenience, it has gradually shown its unique charm in film and television props; exhibitions; advertising; models and other fields. Foam sculpture products have the advantages of a lightweight, low price, and short production cycle.
Widely used in exhibition venues, outdoor advertising, commercial space layout, wedding layout, shopping malls, cultural squares, festival decoration, branding visual identity, Christmas venue set, entertainment venue set, film and television model props, courtyard landscape and indoor and outdoor relief Murals, etc. You can also customize large-scale handicrafts, theme park restaurant buildings, community landscapes and the decoration of original buildings according to requirements.
Compared with Fiberglass, foam sculpture has better weather resistance, lightweight, and high strength, the relative density is between 1.5 ~ 2.0, only 1/4 ~ 1/5 of carbon steel, but the tensile strength is close to, or even exceeds carbon Steel, and the specific strength can be compared with high-grade alloy steel.
Corrosion resistance is good. Fiberglass is a good corrosion-resistant material. It has good resistance to the atmosphere, water, and common concentrations of acids, alkalis, salts, and a variety of oils and solvents. It has been applied to all aspects of chemical anticorrosion and is replacing carbon steel, stainless steel, wood, non-ferrous metals, etc.
It has good electrical properties and is an excellent insulating material used to make insulators. It can still protect good dielectric properties at high frequencies. Microwave transmission is good and has been widely used in radomes.
Good thermal performance, low thermal conductivity of Fiberglass, 1.25 ~ 1.67kJ / (m · h · K) at room temperature, only 1/100 ~ 1/1000 of metal, is an excellent thermal insulation material. It is an ideal thermal protection and ablative material under transient ultra-high temperature conditions, which can protect the spacecraft from high-speed airflow above 2000 ℃.
① Various structural products can be flexibly designed according to needs to meet the requirements of use, which can make the product have a good integrity.
② Materials can be fully selected to meet the performance of the product. For example, it can be designed to be resistant to corrosion, instantaneous high temperature, particularly high strength in a certain direction of the product, good dielectric properties, etc.
① The molding process can be flexibly selected according to the shape, technical requirements, use and quantity of the product.
② The process is simple and can be molded at one time, and the economic effect is outstanding. Especially for the products with a small number of complex shapes and difficult to form, it also highlights its technological superiority.
At present, the technological methods of foam sculptures are constantly being updated. For example, the coloring and surface treatment of foam sculptures have made rapid progress: the pigments required for coloring foam sculptures are the best acrylic colors, which can be diluted with water and dried It is waterproof and resistant to aging; in addition, advertising colors can be used to color foam sculptures.
Specific coloring methods: divided into two types: brushing with a brush and spraying with a spray gun.
1. The general procedure of using the brush method is: first brush the work with white latex, allow it to dry naturally, and then apply the desired acrylic color in layers.
2. The principle of painting with a spray gun does not require the use of white latex, as long as the acrylic paint is added with water and sprayed directly on the work.
No matter what method is used for coloring, color correction is the key to the success of coloring works. Therefore, beginners should first learn some coloring common sense. For those who are new to color, it ’s very important It is necessary that it can improve people’s awareness of color in a short time. Foam carving and coloring should be new, clear and uniform.
